Viscosity

In assessing the effect of temperature on the viscosities of water, corn syrup, and acetone, the temperature of the water bath was varied from test to test. At each temperature, with the exception of water at 25.3℃, three trials were run in which the time that it took for the material to travel between the marked lines on the viscometers was recorded. By having multiple data points for each test, a greater level of certainty could be obtained when the time came to analyze the data. For the experimentation

in the past for nanomaterials like CuO, Al¬2o3 and other materials and few in Tio2 and Zro2. Ehsan et al. 2013(1) in their work add copper oxide (CuO) nanoparticles to engine oil and evaluate the produced changes in some of its properties like, viscosity, pour point, and flash point of nanolubricants at different concentrations (0.1, 0.2, and 0.5 wt.%), and also their thermal conductivity coefficient as for quality parameters which are effective in the functionality of engine oil are checked. From

Investigation 4.2: Factors Affecting Viscosity Question How does changing the temperature (°C) of glycerin affect the viscosity s -1 of glycerin (l), when tested by dropping a marble from a constant height into the glycerin (l) and timed with a stopwatch until the marble hits the bottom? Design Independent Variable: The independent variable of this experiment is the temperature (°C) of the glycerin (l). Dependent Variable: The dependent variable of this experiment is the viscosity s -1 of the glycerin (l).

citric acid on the rheological properties of cornstarch pastes were studied by steady shear and dynamic oscillatory viscoelasticity, intrinsic viscosity measurements and microscopic observation. The pH of cornstarch dispersion was adjusted between 6.0 and 3.0. The viscosity of the pastes was increased by lowering the pH (between 5.5 and 3.6), while the viscosity of samples with pH below 3.5 decreased further than that of the control (pH ) 6.3). Citric

substances are formed. We can determine a physical change by using our 5 senses and a physical change is always reversible. Did you know that viscosity, friction, and density are all examples of a physical property. Well viscosity is the measure of the liquid's resistance to flow. It is also known as the thickness of a liquid. According to RheoSense, viscosity basically is the friction between the molecules of a liquid. Friction is basically the resistance that one object/substance encounters when

“silica” and liquid to determine how the silica content affects its viscosity and relates to potential dangers of a volcanic eruptions. For this experiment to be successful, you must know some key background information. Silica is a solid compound which is present in magma and influences its properties, viscosity is what we call a fluid's resistance to flow. These two core idea’s work together; high silica equals high viscosity, which traps more gases, and leads to a more explosive volcanic eruption

Introduction In this experiment, the focus will be the synthesis and characterization of biodiesel fuel. Biodiesel seems to have become the substitute for fossil fuel. It can also be an alternative for the petroleum-based biodiesel. By having renewable resources such as corn, soybeans, peanuts and other makes biodiesel a viable option. Using these resources wouldn’t help alleviate the problems with fossil fuel in the US. Biodiesel is produced from the transesterification reaction of vegetable

The industries standard for this are set by ISO standards. The minimum cleanliness level the oil must have is ISO 18/16/13. Each number in this number code represents the maximum allowable number of particles in the oil greater than 2 microns, 5 microns, and 15 microns in size respectively. Hard to implement in our design (can’t justify this concisely) not really necessary? The filtration system configuration can be seen below in Figure 4. The pump draws the oil out of the sump and through a

Task 2 – P2 A Newtonian fluid is a fluid that exhibits constant viscosity regardless of any external stress applied to it, like mixing or a sudden application of force. Like water; this flows in the same direction regardless of whether it’s left alone or agitated. A Newtonian fluid, by definition, can only be affected by pressure and temperature together, or temperature, but not pressure on its own. Water The viscosity of water can be affected by temperature, and by pressure and temperature, but

Introduction: In the experiment “White Before Your Eyes” four various white powders were experimented on using various liquids (baking soda, cornstarch, sugar and a mystery powder). The purpose of this experiment was to discover what powder/mixture of powders the substance was. Cornstarch was the next powder experiment on. Cornstarch is a white, soft powder generally used as a thickening agent in liquid-based foods such as soups or sauces. When mixed with lower temperature liquids, it forms a past/slurry
